My problems were like yours. Upset stomach, pain left high, left low and right low. It kind of took turns, but no pain in gallbladder area. Back aches here and there.
US said gallstone and inflammed gallbladder and thickened walls.
Came home from surgeon and found curezone jumped into liverflushing, now more than 2 years ago, and much later learned about healthier eating etc.
Started liverflushing right away. After 10 month gallbladder healed, but still had stone. I am now symptom free, but I still flush. This month I will see my doctor I will ask for US, because I am curious what the stone is doing or if it is still there.
For years I thought I had bowel problems, because that is what it felt like.
